I just reproduced the same error on a stock zencart using the sandbox. This generated the following 2 logs.

It seems that their UK systems are still not in sync with the rest of their operations ...

The following may provide some relief, although I'm surprised that nobody else is reporting the same issue ...

Find this file: /includes/modules/payment/paypal/paypal_curl.php
around line 204 you'll see this:if (($fname . $lname) !== null && !isset($values['NAME'])) { $values['NAME'] = $fname . ' ' . $lname; }Try replacing those 3 lines with this:```
$values['FIRSTNAME'] = $fname;
$values['LASTNAME'] = $lname;
if (isset($values['NAME'])) unset ($values['NAME']);

Thanks i will try that in a moment and report back.

I expect its something that has changed recently because it has worked fine for me before now. I have put quite a few tests through and also about 6 real orders through. The last one being about 2 weeks before this problem.

It failed in the sandbox but worked fine live.

In the sandbox the error was

 Error (5 <!-- Invalid merchant information: 10501-This transaction cannot be processed due to an invalid merchant configuration. -->)

At least it works live now which is the main concern.

FYI the refund from the control panel was fine also.

It is strange no one else has reported it. When i came to the forums i was expecting to find a post or 2 but could not find anything.

Thank you very much for your help it is much appreciated.

Thanks DrByte.

The problem still exists but thankfully, that work around is good for live transactions. Not tried sandbox, but they where working before anway.
